Van Driver Threatened With Catapult
Police are investigating a failed robbery in Totton, where a van driver was threatened with a catapult.
At about 1pm on Friday 6 June, a 24-year-old Romsey man was in the recycling area of Asda supermarket at Totton. He was driving a white Ford Connect van when a man got into the van, threatened him with a catapult and demanded money.
The driver was further threatened when he said he had no money. The driver then got out of the van, locked the suspect inside and went for help.
When he returned, the suspect had broken the front passenger window and escaped with an accomplice.
A 22-year-old Southampton man has been arrested and bailed, pending further enquiries, until 11 July.
Police Staff Investigator Richard Lynham is appealing for contact from witnesses:
"We need to hear from anyone who witnessed this incident in the Asda car park, near the Esso garage. It was a busy Friday lunchtime.
"Did you witness the incident? If so, what did you see? Did you see people milling about in the area? Did you recognise any of these people?"
Anyone with information is asked to contact Lyndhurst CID on 101.
640 men were killed when the South African troop carrier was hit by a cargo ship in 1917.
The 79-year-old man suffered a serious head injury in the Cranmer Road car park in Winton.
